CD BioSciences is committed to providing our customers with a wide range of advanced biophysical techniques to help them analyze the hygromechanical behavior of the S2 cell wall layer of wood. Our dedicated research team will provide you with the necessary technical support to study the swelling/shrinkage anisotropy of wood cell wall material.
As a hygroscopic material, wood can respond to changes in environmental humidity by changing its geometry, i.e. the cellular structure of the wood swells during wetting and shrinks during drying. The hierarchical microstructure of wood results in anisotropic mechanical and swelling behavior across multiple scales. Although moisture-induced deformation originates at the subcellular scale, explanations for the anisotropic nature of wood swelling/shrinkage can be found at the cell wall scale and at the cellular architecture levels.
In situ analyses of wood swelling and shrinkage have been carried out at the cellular level by techniques such as microscopy and microcomputer X-ray tomography. However, little is known so far about the swelling/shrinkage properties of wood cell walls. It has been suggested that the S2 layer within the cell wall makes a major contribution to the swelling/shrinking behavior, particularly in the transverse plane of the wood. It is therefore necessary to study the swelling behavior of the S2 cell wall layer in wood, which seems to be a key factor in the anisotropic swelling behavior of wood at a higher level.
